Be it known that we, JAMES E. MCLAUGH- LIN and DONAT BoRDELEAU, subjects of the King of England, residing'at Grand Mere,

-in the Province of Quebec, Dominion of Canada, have inventedcertain new and use ful Improvements in Seal-Locks forFreight- Car Doors; and theydo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in seal locks for freight carp "the ears 2 and 3 is a guide member 14 on doors.

An object of the invention resides in the provision of a lock which will be easily operable and which consists, essentially, of a bolt and socket, which bolt will swing to a position where it will permit the locking hasp to be readily disengaged and which will move automatically to a position in alinement with the socket member so that it may be thrust therein conveniently.

With this and other objects in view, such as will appear as our description progresses, our invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

In the drawing:

Figure 1 is a front elevation of the device showing the same in its locking position with a hasp and seal inplace thereon;

Fig. 2 is a side elevation thereof;

Fig. 3 is a similar view with the bolt withdrawn from the socket;

Fig. 4 is a vertical sectional view on line 44 of Fig. 1;

Fig. 5 is a similar view with the parts in the positions shown in Fig. 3 of the drawing, and

Fig. 6 is a transverse sectional view on line 66 of Fig. 1.

characters wherein like parts are indicated Referringto the drawing by reference by like characters throughout the several views: 7

The invention as illustrated in the drawing includes a bracket 1 on which a pair of ears 2 and 3 areformed, the said ears being located adjacent the ends of the bracket.

The upper ear is provided with a socket 4 for a purpose which will later appear. Formed integral with the lower ear 3 are flanges 5. Slidably mounted in a rectangu- Specification of Letters as.

formed which is adapted to contact with the 'saidear 3 and limit the upward movement of the bar. Pivotallyjsecured to-the upper end of this bar 7 is a lockingbolt which inlar opening 6 in the lower ear?) isa bar 7 on 'the'lower end of which a-finger piece 8 is portions 12 of the fingers 11 are adapted to I extend. Formed on the bracket 1" between which the body portion of the locking bolt is adapted to rest.

From this construction it will be seen that when the bolt portion 10 is withdrawn from the socket 41in the ear 2, the fingers 11 will ride along the bracket 1 until the toe portions 12 strike the upper face of the ear 3 at which time they will ride upon this face and because of the peculiar formation of the said fingers 11, the locking bolt will be moved upon its pivot to a position such as shown in Fig. 3 of the drawing, at which time the hasp 15 may be withdrawn from the ear 2. Now as the bar 7 is pushed upwardly by means of the finger piece 8, the fingers 11 of the locking bolt will again ride upon the bracket 1 and the said bolt will be swung about its pivot until the body portion thereof engages the guide member 14, which guide member will arrest the pivotal movement but will allow the locking bolt to have further sliding movement. This guide member 14 will arrest the locking bolt so that the bolt portion 10thereof will aline with the socket member 4 and so that the said bolt portion will penetrate the socket. This bolt portion is provided with a slot 16 through which a suitable seal 17 may be engaged.

It will thus be seen that we have provided a seal lock, the locking bolt of which is pivotally mounted so that it will aline autoengaged from the earwith which it engages. 7

While we have illustrated and described a particular'embodiment of our invention, 1t has merely been for the sake of convenience and we do not wish to be limited to that particular embodiment, as it is obvious that numerous changes may be made in the details bracket "including an "ear provided with a socket, of a slidably andipivntallyamonnted locking bolt having a portion adapted to engage in saidssocket, [the :Said ibjol't being constructed and arranged to move pivotallw M19011 its-Withdrawal from thesocketand-to valtne w th .the'socket when moved :1-1-1 a;.d1- -rect1on towand the :same and means for op- 2 Irma seal lock, the combination with ia ubnaoket ;i-nc11.-1d-in-g ianiear provided with a s -soeket., o:f a locking bolt sslzidahly and pivot- M al ly mounted, the saidbolt beimg-constmctfled and arrangedtomove out OfJaJI'iIIGmGIIt with thesocket when withd rawn thenezfrom and to move into alinenient, automatically, when moved towardthe same.
